I'm also unhappy with the current behavior. It's a source of hard to find bugs, and, IMO,
not a very useful feature. PHP has provisions for handling varargs, so why not stick with them?

I think current behaviour is fine, Module functions dont have to check how many arguments they have,
they can if they want but there are some that dont for various reasons.
The current situation seems to work ok and there is no reason why passing extra arguments is an
error as they dont effect the running of the program.

I know it may break a lot of scripts that has written poorly. I'm not suggesting to change the
behavior immediately, without a ini entry or build option. :)
Without proper variable length parameters handling, too many parameters for a function is obvious
programming mistake. This behaviour is inconsistent with functions defined by modules also.
Zend is better to have option to warn, if caller called a user defined functions with too many
arguments. IMHO.
However PHP is scripting language, adding too many features to language is not good idea. Just a
suggestion.

Changing this would break a lot of scripts.
And what's wrong with specifying too many parameters? If you don't use them explicitly,
they don't influence the function, so why care about them?

Currently, it seems PHP is designed NOT to report errors for too many paramaters for user defined
functions.
"..." for variable length paramters. Raise error without "...", for example.
function foo($var1, $var2, ...)
assert(count(function_get_args()) <= 3);
or like can be used to check num of paramters, but module functions checks num of parameters. User
functions are better to behave the same way by default. IMHO.
